Orifices
Four (4) orifice sizes are supplied with the
planter. Size 22, 30, 39 & 51. The planter comes
with size 39 assembled at the nozzle bodies.
System pressure should be in the 30 to 60 psi
range to insure proper distribution across all
rows. If the system pressure is below this for the
quantity of fertilizer you are applying use a
smaller orifice. If the pressure is too high use a
larger orifice. The same size orifice must be used
on all rows.
A multitude of orifices are available locally from
your nearest Tee Jet distributor.
Use the following formula to determine the best
orifice for your application and desired rate.
Once determined, use the Orifice Plat chart from
Tee Jet to determine exact PSI, adjust pressure
as needed.

operating at desired 10 GPM @ 7 MPH.
NOTE: On splitter planters if only using
standard rows the intermediate rows liquid
supply must be shut off. To do this remove
the orifices from the interplant row nozzles
and install the supplied block off plates and
seals. (See pictures on the following page)
